Wave instabilities of a collisionless plasma in fluid approximation [PDF]
Contributions to Plasma Physics, 2010 Wave properties and instabilities in a magnetized, anisotropic, collisionless, rarefied hot plasma in fluid approximation are studied, using the 16-moments set of the transport equations obtained from the Vlasov equations. These equations differ from the

Approximate Controllability of Second-Grade Fluids [PDF]
Journal of Dynamical and Control Systems, 2020 This paper deals with the controllability of the second grade fluids, a class of non-Newtonian of differentiel type, on a two-dimensional torus. Using the method of Agrachev-Sarychev [1], [2] and of Sirikyan [26], we prove that the system of second grade fluids is approximately controllable by a finite-dimensional control force.

Approximation of Time-Dependent Viscoelastic Fluid Flow: SUPG Approximation [PDF]
SIAM Journal on Numerical Analysis, 2003 Summary: We consider the numerical approximation to the time-dependent viscoelasticity equations with an Oldroyd B constitutive equation. The approximation is stabilized by using a streamline upwind Petrov-Galerkin (SUPG) approximation for the constitutive equation. We analyze both the semidiscrete and fully discrete numerical approximations.

On numerical approximations to fluid–structure interactions involving compressible fluids
Numerische Mathematik, 2022 In this paper we introduce a numerical scheme for fluid-structure interaction problems in two or three space dimensions: A flexible elastic plate is interacting with a viscous, compressible barotropic fluid. Hence the physical domain of definition (the domain of Eulerian coordinates) is changing in time.

Fluid Approximation of Pool Depletion Systems [PDF]
, 2016 Today’s most of high performance computing applications use parallel programming paradigms to reach the desired efficiency objectives. In particular, they divide the problem into small elements that can be solved in parallel by as many computing devices as available. Some examples are Apache Spark, the evolution of Hadoop and map-reduce, GPGPU (General

State Equations in Stochastic Process Algebra Models
IEEE Access, 2019 State equations are usually used for structural or qualitative analysis, such as deadlock checking, in P/T systems. In this paper, we instead consider timed state equations in stochastic process algebra models, to derive quantified dynamic information on

High Speed Dynamics of Collapsing Cylindrical Dust Fluid [PDF]
, 2003 We construct approximate solutions that will describe the last stage of cylindrically symmetric gravitational collapse of dust fluid. Just before the spacetime singularity formation, the speed of the dust fluid might be almost equal to the speed of light

Diffusion models for double-ended queues with renewal arrival processes
Stochastic Systems, 2015 We study a double-ended queue where buyers and sellers arrive to conduct trades. When there is a pair of buyer and seller in the system, they immediately transact a trade and leave.
